1、高考英语外刊阅读模拟强化训练 七选五专题十七Next time youre with a loved one, try an awkward experiment: Take a moment of silence and gaze into each others eyes. _1_“Theres something in that looking that has meaning, sustainable meaning,” says Joy Hirsch, a neuroscientist at Yale School of Medicine. “The mechanism for co
2、nnection has never really been understood.” _2_Hirsch and other neuroscientists have only recently begun to acquire meaningful data mapping the interplay. Such work has promising potential in the realms of autism and other behavioral psychology research.Eye contact undoubtedly holds power over our s
3、ocial connections. On the neurological level alone, a vast array of variables has limited our understanding of how eye contact informs the brain. _3_Several years ago, her team figured out how to adapt an existing neuroimaging tool called functional near-infrared spectroscopy, or fNIRS, for the purp
4、ose of analyzing the brains of two people simultaneously during natural interactions._4_Specifically, fNIRS experiments have demonstrated that in-person eye contact seems to be connected to a brain cluster associated with language production and reception. _5_In simple terms: “The eyes have privileg
5、ed access to large parts of the brain,” says Hirsch.【Discover (May, 2023)】A. Faces and brains work together like locks and keys.B. In their research, Hirsch has revealed a robust region of the brain that is associated with eye contact.C. By the time you reach about four seconds, things will probably
6、 start to feel uncomfortable.D. It is also associated with the primary somatosensory cortex, which is fundamental to processing sensations.E. Hirschs experiments have also revealed the unique tendency for two brains to synchronize patterns during eye contact.F. In fact, many questions remain unanswe
7、red about how eye contact might influence social interactions.G. But Hirschs Brain Function Laboratory has committed to overcome these research limitations, thanks to new technology.Sauropod Dinosaurs（蜥脚类恐龙）were giants of the Jurassic and Cretaceous periods. _1_And while there are multiple reasons w
8、hy these reptiles grew to such imposing sizes, paleontologists(古生物学家) are still uncovering the biological particulars. Among them, researchers have learned, were cushioned feet.Paleontologists have been pondering sauropod feet for a long time. Footprints and trackways left by these dinosaurs show th
9、at the bottoms of their feet had soft pads on the underside of the toes. _2_Understanding how an animal holds their feet is a complicated task. Some animals, such as bears and humans, are plantigrade. _3_But many other animals, like cats and birds, are digitigrade effectively standing on tiptoe. For
10、 a long time, paleontologists thought sauropods were flat-footed, plantigrade animals. But Jannel of the Natural History Museum notes that the dinosaurs have an arrangement that is a little strange. _4_Eventually, instead of switching foot postures, the pads at the bottom of their feet formed cushio
11、ns that allowed more contact with the ground.The research resolves what paleontologists have only been able to speculate about for 120 years: The pads were part of a constellation of features that opened evolutionary opportunities for sauropod dinosaurs to become exceptionally enormous. Egg-laying,
12、forgoing chewing and lightweight bones filled with air sacs also had their roles to play. _5_【Discover (May, 2023)】A. That flexibility may have helped redistribute weight as they moved.B. This means the entire foot, from toes to heel, touches the ground.C. They allowed Sauropod Dinosaurs to surpass
13、whats been possible for any land-dwelling mammal since.D. The largest species could reach lengths exceeding 100 feet, with weight that could top 80 tons.E. The earliest sauropod ancestors were digitigrade.F. However, using virtual, 3D models of feet from sauropod dinosaurs, the researchers were able
14、 to study the presence or absence of a foot pad.G. But it wasnt until recently that researchers understood just how important these pillowy pedals were to the evolution of truly gargantuan dinosaurs.From hospital staff and emergency responders to service-industry employees, shift workers make up abo
15、ut one-fifth of the U.S. workforce. _1_Reducing those risks could benefit millions of working adults.These health consequences can manifest in a variety of ways. “Working irregular or night shifts generally suppress the bodys natural production of melatonin,” says Sabra Abbott, a sleep medicine spec
16、ialist. Melatonin is crucial in sleep regulation._2_Shift workers usually are asleep during the day when we are meant to be alert, which can result in short and fragmented sleep. _3_A person with SWSD may have irritability or mood problems, an increased likelihood of work-related errors, poor coping
17、 skills, impaired social functioning and various health issues.Disrupting the circadian rhythm isnt just about sleep; it also affects how the entire body functions, including the cardiovascular and immune systems, as well as overall metabolism, digestion and hormonal balance. _4_To minimize the heal
18、th risks of having nontraditional work hours, experts recommend keeping a regular sleep schedule even during off-work periods. _5_“Make time for sleep during your off time, making sure that you have a dark, quiet and uninterrupted place for sleep,” Abbott adds.【Discover (May, 2023)】A. Try to find a
19、compromise sleep window that is relatively similar on days on and days off.B. Their findings suggest that the health impacts of shift work persist over time.C. Its suppression meddles with the bodys circadian rhythm, or our internal clock.D. Such adjustments include ensuring that employees have the
20、same break time every day.E. This puts them at risk of a condition called shift work disorder (SWD) or shift work sleep disorder (SWSD).F. Research shows that shift work is associated with a host of health concerns.G. Thats why irregular or night shifts are associated with the increased risk for obesity, hypertension, cardiovascular disease and diabetes even cancer.答案CFGBDDGBECFCEGA学科网（北京）股份有限公司
